| Abstract |
This paper proposes a systematic procedure to evaluate, compare and select different modulationtechniques for a medium voltage variable speed drive. Several indicators are proposed to be analyzed,mainly based on thermal analysis, voltage limitations, dc bus evaluation and load current quality. Thesuggested procedure is evaluated on a simulation based analysis in a 6.6 kV adjustable speed drivesystem with a 5-level H-bridge neutral point clamped (HNPC) inverter topology and diode front end(DFE) as rectifier. The use of selective harmonic elimination (SHE) with different number of anglesand space vector modulation (SVM) is assessed depending on the load demands (output frequency,modulation index, etc.). |
